Abstract
Description
L'invention concerne les implants dentaires.The invention relates to dental implants.
Un implant dentaire est l'équivalent prothétique de la racine d'une dent. Sans qu'il y paraisse, la racine d'une dent est dotée, sous un très faible volume, de propriétés étonnantes. Elle doit pouvoir subir des contraintes de l'ordre de dix à trente kg par cm2, son matériau doit être à même de résister aux contraintes mécaniques engendrées par la mastication.A dental implant is the prosthetic equivalent of the root of a tooth. Without it appearing, the root of a tooth is endowed, under a very small volume, with astonishing properties. It must be able to withstand stresses of the order of ten to thirty kilograms per cm 2 , its material must be able to withstand the mechanical stresses engendered by chewing.
La racine sert en fait à transmettre les efforts masticatoires des muscles à la couronne dentaire via les os maxillaires. Le contact entre l'assise osseuse et la racine a donc une importance déterminante. Le problème est qu'un os n'est pas une structure homogène : sous ses parois corticales très résistantes s'étend sa zone médullaire, d'aspect spongieux, qui offre une assise mécanique négligeable pour un implant. Un implant dentaire doit donc impérativement traverser la zone médullaire pour s'ancrer fermement dans les parois corticales. Les implants dentaires actuels nécessitent donc au moins 8 à 15 mm de structure osseuse pour être mis en place. Cette mise en place se fait par vissage, après forage de l'os maxillaire inférieur ou supérieur.The root is actually used to transmit the efforts masticatory muscles to the dental crown via the bones maxillary. The contact between the bone support and the root therefore has a decisive importance. The problem is that bone is not a homogeneous structure: under its walls very strong cortices extends its medullary area, spongy in appearance, offering a mechanical base negligible for an implant. A dental implant must therefore It is imperative to cross the medullary area to anchor firmly in the cortical walls. Implants dental devices therefore require at least 8 to 15 mm of bone structure to be put in place. This implementation place is done by screwing, after drilling the maxillary bone lower or higher.
Cette technique n'est cependant applicable que pour les patients présentant un support osseux suffisant, ce qui correspond à une classification SD 1 en implantologie.However, this technique is only applicable for patients with sufficient bone support, which corresponds to an SD 1 classification in implantology.
Cette classification est basée sur la hauteur du plancher du sinus maxillaire dans la technique d'implants bicorticaux; SD1 correspond à une hauteur de plancher supérieur à 10mm. This classification is based on the height of the maxillary sinus floor in the implant technique bicortical; SD1 corresponds to a floor height greater than 10mm.
Suivant la même classification, SD2 correspond à une hauteur de plancher comprise entre 8 et 10mm, SD3 entre 5 et 8mm, SD4 entre 0 et 5mm (ce qui requiert un comblement) .Following the same classification, SD2 corresponds to a floor height between 8 and 10mm, SD3 between 5 and 8mm, SD4 between 0 and 5mm (which requires filling).
En outre, après mise en place du support de l'implant, on attend généralement près de cinq mois avant de pouvoir mettre la couronne dentaire en charge.In addition, after placing the support of the implant, we usually wait almost five months before we can put the dental crown in charge.
On connaít par EP- 336 082 un pivot dentaire à pas de vis servant à fixer une couronne dans la racine d'une dent. Des orifices sont prévus dans le pivot pour injecter un ciment axialement. Une telle technique n'est toutefois pas transposable au maxillaire. It is known from EP-336 082 a dental pivot to not of screw used to fix a crown in the root of a tooth. Orifices are provided in the pivot to inject a cement axially. Such a technique is, however, not not transposable to the maxillary.
EP-A-0 412 845 décrit un implant muni de projections circulaires et muni d'une perforation transversale pour implantations classiques, qu'on peut considéré comme le plus proche de l'implant inclus dans la présente invention.EP-A-0 412 845 discloses an implant provided with projections circular and with transverse perforation for conventional implantations, which can be considered the closer to the implant included in the present invention.
US-A-5, 797, 741 décrit une méthode d'implantation par clavettage.US-A-5,797,741 discloses a method of implantation by clavettage.
Un guide de forage à table coulissante est fixé par vissage sur l'implant.A sliding table drill guide is screwed on the implant.
Après perforation latérale du maxillaire, une à deux clavettes introduites transversalement immobilisent l'implant. After lateral perforation of the maxilla, one to two transversely inserted keys immobilize the implant.
L'os alvéolaire a pour rôle le soutien des dents.
Lorsque celles-ci disparaissent, l'os, qui a perdu sa
fonction propre, se résorbe. L'os peut également se
dégrader (pour d'autres raisons (affections diverses,
tumeurs, etc.).
Pour les personnes correspondant à des stades de
détérioration plus élevés (SD 2, SD 3 et SD 4) les parties
corticales du support osseux ne présentent plus une
épaisseur suffisante pour la mise en place d'un implant.
Dans ce cas, on réalise une greffe osseuse dans le sinus
maxillaire pour augmenter l'épaisseur du support osseux. On
utilise comme greffons des esquilles d'os prélevées sur le
patient lui-même. Après ossification (qui prend elle-même,
généralement, de l'ordre de 5 mois), on peut placer un
implant selon les principes décrits ci-dessus.The role of the alveolar bone is to support the teeth. When these disappear, the bone, which has lost its proper function, is reabsorbed. The bone can also be degraded (for other reasons (various conditions, tumors, etc.).
For persons corresponding to higher stages of deterioration (
Le but de l'invention est de pouvoir traiter les stades SD2 ou supérieurs sans recourir à un traitement lourd. Un autre but de l'invention est de pouvoir obtenir une mise en charge immédiate de la dent implantée.The object of the invention is to be able to treat SD2 or higher stages without treatment heavy. Another object of the invention is to be able to obtain immediate loading of the implanted tooth.
L'objet de l'invention est un nécessaire adapté à la mise en place d'un implant dentaire qui comprend :
- un implant tel que décrit ci-dessous,
- un fluide biocompatible durcissable;
- un dispositif de repérage de l'orifice latéral de l'implant comprenant une languette amovible solidarisable sur la tête de l'implant
- un dispositif d'injection à aiguille creuse permettant, l'implant étant en place, d'injecter le fluide biocompatible durcissable, au-travers de l'os, dans la cavité interne de l'implant par l'orifice latéral.
- an implant as described below,
- a curable biocompatible fluid;
- a device for locating the lateral orifice of the implant comprising a detachable detachable tab on the head of the implant
- a hollow needle injection device allowing the implant in place to inject the curable biocompatible fluid through the bone into the internal cavity of the implant through the lateral port.
Les dimensions de cet au moins un orifice latéral permettent l'introduction par une aiguille creuse d'un matériau durcissable dans la cavité interne.The dimensions of this at least one side port allow insertion by a needle hollow of a curable material in the internal cavity.
La cavité interne de l'implant peut aussi présenter un orifice axial à son extrémité distale.The internal cavity of the implant may also have an axial orifice to its distal end.
Cet au moins un orifice latéral de l'implant présente de préférence une section ovale, le grand axe de cette section ovale s'étendant dans un plan perpendiculaire à l'axe de la racine.This at least one lateral orifice of the implant preferably has an oval section, the major axis of this oval section extending in a plane perpendicular to the axis of the root.
La longueur axiale de l'implant est, de préférence, comprise entre 3 et 8 mm.
- le cas échéant, une spatule rétractable dans une aiguille creuse ; de préférence, l'aiguille creuse est en un métal à mémoire de forme, capable de passer d'une forme initiale droite à une forme courbée
- if necessary, a retractable spatula in a hollow needle; preferably, the hollow needle is made of a shape memory metal, capable of passing from a straight initial shape to a curved shape
D'autres particularités et avantages de l'invention
ressortiront de la description ci-après de modes de
réalisation particuliers, référence étant faite aux
dessins, dans lesquels :
Les Fig. 1 a 3 montrent trois variantes possibles de 1' implant 1 de l'invention.Figs. 1 to 3 show three possible variants of Implant 1 of the invention.
Cet implant présente une tête 2 classique, destinée à
supporter une prothèse dentaire et une racine filetée 4 en
substance cylindrique.This implant has a
Une série de rainures longitudinales 6 ménagées le long de la racine permettent à l'implant de tarauder la paroi de l'alvéole pendant sa progression dans la structure osseuse. A series of longitudinal grooves 6 formed on along the root allow the implant to tap the wall of the cell during its progression in the structure bone.
Près de sa partie distale, la racine 4 est munie d'un
orifice latéral 8 de forme sensiblement ovale qui débouche
dans une cavité 10 de la racine 4, dont l'extrémité est
donc creuse.Near its distal part, the
L'orifice latéral 8 peut déboucher à différents
endroits de la racine 4 (voir Fig. 1 et 2). La racine 4
peut être munie d'un orifice axial 12 débouchant vers sa
pointe.The lateral orifice 8 can lead to different
places of root 4 (see Fig. 1 and 2). The
La Fig. 4 montre l'implant 1 après son introduction
dans un os maxillaire 14. Comme on peut le constater, la
racine 4 traverse la paroi corticale 16 dure de l'os et
plonge dans la zone médullaire 18, spongieuse, de l'os, qui
contient la moelle. La position de l'orifice latéral 8 sur
la racine 4 est telle que cet orifice 8 débouche dans cette
zone médullaire 18 de l'os 14.Fig. 4 shows the implant 1 after its introduction
in a
La Fig. 5 montre une phase ultérieure de la mise en
place de l'implant 1 : un dispositif de repérage 20
indiquant la position angulaire de l'orifice latéral 8, (en
l'occurrence une languette calibrée), a été clipsé sur la
tête 2 de l'implant,. L'aiguille 22 d'un dispositif
d'injection 23 a été introduite, en perforant l'os de la
mâchoire, jusqu'à l'embouchure 8 de la cavité 10 de la
racine 4. La présence de la languette de repérage 20 (en
combinaison avec l'imagerie médicale) rend le pointage très
sûr. A ce moment, on injecte au travers de l'aiguille un
produit biocompatible durcissant 24 (ciment, polymérisant
ou précipitant) dans l'implant 1. Cette injection est
poursuivie jusqu'à ce que le produit durcissant 24,
débordant de la cavité 10, remplisse le volume
périprothétique, et les alvéoles médullaires adjacentes.
L'expansion du produit 24 peut être favorisée en retirant
progressivement l'aiguille tout en poursuivant l'injection,
comme montré à la Fig. 5. Fig. 5 shows a later phase of the implementation of
place of the implant 1: a tracking
Après la prise complète du produit durcissant 24,
l'implant 1 est solidement implanté dans l'os maxillaire 14
et peut être mis en charge sans délai.After the complete setting of the hardening product 24,
the implant 1 is firmly implanted in the
La Fig. 6 est une vue en coupe transversale de
l'implant 1. Comme représenté, l'aiguille 22 peut être une
aiguille droite classique. Cependant, on peut également
utiliser une aiguille courbe 25, ou, mieux encore, une
aiguille à mémoire de forme dont la pointe se recourbe
après son introduction. L'intérêt d'une aiguille courbe 25
est d'augmenter le volume d'injection du fluide durcissable
des deux côtés de l'implant 1, jusqu'au bord controlatéral
de la portée corticale de l'os, puis, par retrait de
l'aiguille 22, 25 jusqu'au bord ipsilatéral au point
d'entrée de l'aiguille 22, 25.Fig. 6 is a cross-sectional view of
1. As shown, the
On a la possibilité d'injecter le fluide biocompatible durcissable par la lumière du trou prothétique qui peut être en communication avec l'apex de l'implant (voir la Fig. 2), ceci peut être réalisé par la tête de l'implant, par un embout prothétique placé sur cette tête ou par une aiguille mise en place à travers l'implant. Cette technique est intéressante au niveau mandibulaire.It is possible to inject the biocompatible fluid curable by the lumen of the prosthetic hole that can be in communication with the apex of the implant (see Fig. 2), this can be achieved by the head of the implant, by a prosthetic tip placed on that head or by a needle set up through the implant. This technique is interesting at the mandibular level.
Les avantages du présent implant sur les implants classiques sont multiples. En effet, il n'est plus nécessaire d'attendre plusieurs mois avant l'ossification complète de la zone périprothétique, ce qui abrège considérablement le calvaire des patients et supprime les interventions intermédiaires multiples avant la pose des couronnes sur l'implant.The benefits of this implant on implants classics are multiple. Indeed, it is no longer necessary to wait several months before ossification complete periprosthetic area, which shortens patients' suffering and eliminates the multiple intermediate interventions before the crowns on the implant.
En outre, le produit durcissant 24 est progressivement colonisé par l'organisme et remplacé par une assise osseuse solide.In addition, the hardening product 24 is progressively colonized by the body and replaced by a bone base solid.
Enfin, la longueur de l'implant est considérablement réduite (3 à 8 millimètres, en fonction de la hauteur disponible, contre 8 à 15 mm pour un implant classique), ce qui permet d'implanter des dents même chez des patients inopérables par les méthodes classiques.Finally, the length of the implant is considerably reduced (3 to 8 millimeters, depending on the height available, versus 8 to 15 mm for a conventional implant), this which allows to implant teeth even in patients inoperable by conventional methods.
Par ailleurs, si le patient présente une épaisseur
d'os maxillaire 14 vraiment trop réduite il reste néanmoins
possible de poser un implant 1 suivant l'invention en
empiétant sur le volume des sinus maxillaires.Moreover, if the patient has a thickness
Avec un implant classique, cette méthode ne serait applicable qu'en introduisant une opération préparatoire très longue : dont l'ossification des greffons au revers de l'os maxillaire prendra près de 5 mois, jusqu'à l'obtention d'une paroi corticale suffisamment dure et stable pour y visser un implant.With a conventional implant, this method would not applicable only by introducing a preparatory operation very long: including the ossification of grafts on the reverse of the maxillary bone will take almost 5 months, until obtaining a sufficiently hard cortical wall and stable to screw an implant.
Les Fig. 8 et 9 montrent comment il est possible de renforcer la mâchoire au cours de la pose d'un implant de l'invention.Figs. 8 and 9 show how it is possible to strengthen the jaw during the placement of an implant the invention.
Une aiguille 26 est introduite sous contrôle
d'imagerie au travers de l'os maxillaire 14 jusque sous la
muqueuse 28 du sinus maxillaire 30 afin de décoller cette
muqueuse 28. Le décollement est réalisé par une spatule à
mémoire de forme décrite en référence aux Fig. 10 et 11.
Cette aiguille 26 dont la pointe est en diamant ou autre
est creuse et contient un mandrin 32 à mémoire de forme qui
une fois sorti de l'aiguille se déploie pour former une
spatule 26 permettant de décoller la muqueuse. Après repli
de la spatule 26 et retrait du mandrin 32 à mémoire de
forme, un ciment 24 de même composition que précédemment
peut être injecté par l'aiguille 26 dans la poche formée
entre la muqueuse 28 décollée et l'os maxillaire 14, ce qui
permet de récupérer de la hauteur et de visser un implant 1
de taille plus importante.A
On notera que la muqueuse 28 peut être décollée par
injection d'un liquide, d'un gaz ou par décollement manuel,
ou encore par injection directe du polymérisant ou du
précipitant.It will be noted that the
Avec la technique d'implants immobilisés par scellement, on peut envisager de traiter SA2, SA3, SA4, mais aussi des cas mandibulaires où l'ostéoporose a fait disparaítre toute trace de trabéculation au niveau médulaire. Cette technique permettant l'immobilisation primaire (dès le premier temps chirurgical) de l'implant sans avoir un blocage bicortical; et donc une mise en charge immédiate de l'implant.With the technique of implants immobilized by sealing, it is possible to treat SA2, SA3, SA4, but also mandibular cases where osteoporosis has disappear any trace of trabeculation at the level medullary. This technique allows immobilization primary (from the first surgical time) of the implant without having a bicortical blockage; and therefore a setting immediate load of the implant.
